I think it makes it far more interesting to watch, you need to get yourself a HD camera though, 480p is a bit lame. The commentary certainly helps raise the bar though. Hearing what you have to say is a nice reason to watch.
Ive got a ContourROAM2 and for some strange reason the video rendered in 480p and not 1080p. Think I'm going to re-upload, as it won't allow me to view in 1080p.
